Seriously spend your money on the ps4 most of the big games come out on both platforms anyway and why would you want to miss out on a new uncharted game?
Had a buddy over the other day, play station guy. He sat down and played an hour of titanfall. The next day he was at GameStop trading in his ps4. He got the titanfall bundle and with his games they owed him 20. I asked point blank how bf4 compared on both systems. He said he couldn't tell a difference in graphics or gameplay.
I personally haven't messed with ps4 but would like to.
